- ROTARY IMrIiLLING-PUMP.

Zb'dll uiYibm it concern-f Be it known that we, CHARLESVIVWI DRUMf and GEORGEWV; lViiieii'r, citizens 'of "the United State's 'of America, residing at WVebb'C ity, in the county of Jasper and" State of Missouri, haveinventedcertain'neW and-useful Improvements in Rotary Impelling luinps, or which the followingis a full, .clear,.- and exaot'description, reference being part, of "this specification.

had to theaccompanyingdrawings, forming f Our invention relates to a pump havinga peculiar andcontinuous flow of water in large volume,

maybe coiistan'tly maintained during the operation of thepump that is the equivalent of'thefiow derived from a gang of centrifugal pumpsQTo providefor-the attainment oiithe object mentioned, our pump includes a bowlcontaining a pluralityof channels through which the waterinay be independfl ently ejected after entrance into the .bowl and -an impelling Wheel within the 'bowl wherebythe water is forcibly driven into each channel without the occurrence of back ward flow or slippage of the water.

Figure l is in 'part a side elevation and in 4 v part a vertical longitudinal section .of'our pump. Fig.- II is a" vertical cross section -through the bowl of the pump with one of the seetionsof the bowl removed, ,Fi' III ,is a cross section through the impelling wheel on line III-III, Fig. II.

In the accompanying drawings: A desig,

n ates the bowl of our pump which is composed of sections 1 and 2 that are suitably secured to each other. In the bowl section 2 is an inwardly flaring water inlet opening '3'through' which .water may find. entrance into the bowl from a suitable conductingpipe 4 attached to said bowl section, as seen in Fig. Within the bowl --A is an impelling wheel chamber 5 that is provided with a. lateral concavity or extension 6 located in the bowl section 1 and inwhich the.

flanged andcorrespondingly shaped conical hub of the impellingwheel-operates.

7 and 8 are inner and vouter outlet 'chan-. nels within the bowl A, these-channels being preferably produced in part in the bowl section 1 and in part in the bowl section I 2.

The inner outlet channel -7- extends upwardly Specification of Letters .Patent. I Application filed January 4, 1909. Serial No 470,700.

in the bowl from the impelling whel cham her, while the outer outlet channel 8 extends in a curved direction froma point a, (see Fig. II,) atone side of the bowl, therefrom in I a course beneath the inipellin'g wheel chamber,-and then upwardly inv a line parallel'tojhe outlet channel 7. The two outlet channels are se arated at the top of the bowl by a partition in order that separate flows of water may be occasioned through ,the

channels until the water is discharged from the bowl ihto areceiver 10 having commnnication with both of the chai'in els and having jconnected to ita discharge pipe 11 through which the water-is conducted to the point at which it is delivered;

12 designates a housing ring seated in the impelling wheel chamber and extending across the sections 1 and 2 and which matches at with the partition 9 in the bowl A, thereby" serving to complete separation of .the outlet channel 8from' the outlet channel t. In the housing ring is an outlet port 14:

that provides communication between the 'nnpelling wheelchamber and the upper out? let channel 7, and said housing ring is also provided with 'outlet ports I5 and 16 that furnish communication between the impel-,;--

ling wheel chamber and the outlet channel 8. l7 designates an impelling Wheel of star shape having curved peripherah recesses and; ferniingpoints and provided with curved; radial blades 18 which extend'froin the flanged hub 19 located at the rear side of the wheeland occupying the extension 6- of the iinpelling wheel chamber in the bowl A, as seen in Fig. I. The hub of the impel-ling wheel has-a central concavity at its forward side from which the blades of the wheel extend, the concavity 'being located directly-in line with the inlet 3 of the bowl A in order that the water passing into the bowl through said inlet may enter into the said concavity, which serves as a water receiving pocket in the impelling wheel. The inner ends of the blades are disconnected and spaced apart. Each of the blades of the iinpelling wheel is provided with a longitudinal concavity 1-8, (see Figs. I and III-,)

that extends longitudinally of the blade, i

thereby preventing splitting of the water during the rotation of the impelling wheel in the operation, of the. pump.

The impelling wheel of our pumpis operv ated by a suitable shaft 20 mounted in suitable bearings, and which may be driven by of its becoming unfit for service.

through its inlet 3 and, due to the absence of any hub extension at the forward side of the impelling wheel, the water flows into the central concavity or pocket in said wheel and during the rotation of the Wheel is acted upon by the wheel blades. These wheel blades by pressure upon the water as it moves outwardly from the pocketin the impelling Wheel act to impel the water through I the outlet ports 15, 16 and 14 in the housing ring 12 whereby the wateris forcibly driven from the impelling wheel chamber into the separate channels 8 and 7. It will be seen that during this operation the impelling 'wheel blades impel the water through the outlet ports '15 and 16 into the channel 8 and through the outlet port 14 of the channel 7', the impelling action into each channel being independcnt of the impelling action into the other channel, with the consequence of producing a large volume of flow of water from the impellirigwheel chamber. The housing ring 12 is removably seated in the bowl A of our pump and, therefore, any housing ring previously in use may be readily removed from the bowl in the event We claim:

1. ,A pump of the character described comprising a bowl having an inlet, an impelling wheel chamber, an inner channel and an outer channel, both of the channels leading to a common point, a housing ring separatingithe wheel chamber and inner channel from the outer channel, and provided with a port leading to the inner channel and with ports leading to the outer channel and an impelling wheel of star shape having a central concavity, curved peripheral recesses forming points, and curved radial blades spaced apart at their inner ends and extending from the central concavity to the ends of the points.

2; A pump of the character described comprising a bowl having an inlet, an impelling Wheel chamber, an inner channel and an outer channel, both of the channels leading to a connnon point, a housing ring separating the wheel chamber and inner channel from the outer channel, and provided ,with a port leading to the inner channel and with ports leading to the outer channel and an impelling wheel of star shape having a cen-' tral concavity, curved peripheral, recesses forming points, and curved radlal blades having longitudinal concavities and spaced apart at their inner ends and extending from the central concavity to the ends of the points.
